Since entering the fourth quarter, photovoltaic power station around the present investment boom, its impetus, silence for a long time many domestic photovoltaic module manufacturer shipments surged, industry has now signs. Domestic electricity subsidy policy is seen as a key of the entire pv industry profitability.

Distributed in the photovoltaic thermal environment is more vulnerable to everybody, distributed has its own features: first, the distributed power station close to the user transmission and distribution is simple, low loss. Roofing power station near the power user, directly to the nearest grid, power supply to the load, don't need long distance high voltage transmission line, transmission and distribution losses small, the construction is simple and cheap. Second, distributed generation can solve the problem of network operation, has the ability to provide supporting services. Can be combined with power grid operation.
